What is iridocyclitis?

Iridocyclitis is an eye condition in which your iris and the ciliary body become inflamed, or swollen. Other names for this condition are iritis and anterior uveitis.

Your iris is the colorful ring and the pupil (the black center of the eye). The ciliary body is the ring of muscles and tissues located behind your iris that helps your eye focus.

When your iris and ciliary body are inflamed, you may have blurred vision, eye pain, red eyes, a sensitivity to light, and possible vision loss. If you experience these symptoms, see an ophthalmologist (eye specialist) right away to prevent more serious eye conditions.

An eye specialist will determine whether what you’re experiencing is treatable with eye drops that reduce inflammation or is a symptom of a different disease.

Why is iridocyclitis important?

The first records of iridocyclitis come from around 1874. It combines the prefix irido-, meaning “iris,” the combining form cyclo-, meaning “circle,”, and the suffix -itis, which is used to indicate a medical condition that involves inflammation.

We usually can’t determine the exact cause of iridocyclitis because it is often a symptom of another disease or condition. However, people with a specific genetic alteration, people with weakened immune systems, people infected with certain sexually transmitted diseases, and smokers are at higher risk of developing iridocyclitis.
